摘要
为查明西域砾岩的水理特性,通过开展室内颗分、崩解及密度试验等对其进行分析研究。结果表明:受成因、矿物组成等随机性因素影响,西域砾岩的粒度组成与颗粒分布离散性较强;胶结物成分的差异会对砾岩的力学性能造成影响,胶结物胶结能力越强,颗粒间接合越紧密,其密度则相应较大;胶结物成分及胶结类型不仅对西域砾岩的力学性能有影响,对其水理性能也有很大的影响。该结论对于促进新疆地区水利水电事业的健康、快速发展具有十分重要的现实意义。
In order to find out the hydrophysical properties of Xiyu conglomerate, the laboratory tests on its particle distribution, disintegration and density are carried out. The results show that the size composition and particle distribution of Xiyu conglomerate have strong discreteness due to random factors such as genesis and mineral composition. The difference of cementation composition will affect the mechanical properties of conglomerate. The stronger the cementing power is, the closer the indirect adhesion of particles is, and the higher the density is. The composition and type of cementation have great influence not only on the mechanical properties but also on the hydrophysical properties of Xiyu conglomerate. This conclusion is of great practical significance to promote the healthy and rapid development of water conservancy and hydropower in Xinjiang.
